Z'o (Ii/ll wit/m1, it "may concern:

Be it known that I, Josnrn WILLMANN, a subject of the Emperor of Germany, residing at ltome, New York, have invented certain new and usel'ul Improvements in Floats, of

which the following is a specification, refer-.

I fine'adjustment by the operator and'which igi urther efliciently. regulates the feed autoinatically to prevent any "overflow of liquid,

' and consists in the fe tures OfOODSt-I'llCtlOIl and combinations of parts hereinafter fully ,fde scribed and claimed. 1 2'0 the a'ccompanying' drawings illustrating my invention: Figure 1 is a central vertical section of the feed-bowl of a centrifugal separator proyided -with feed regulating devices ponlstrricted in accordance with my invention. Fig.f"2 is a similar view showing a modified form of-construction. 3 is a horizontal section on the line 3''*3'0f Fig. 2. -My said invention'has for'its main object to provide means whereby'the feed to a cen- O 3 tiv'ely uniform by means actuated by the variations in level of the liquid in the feed qbowl d ue to relative variations in feed and .consumption of such liquid, and includes .means whereby the feed may be primarily adjusted by the operator to accord as nearly as possible with the rapidity of consumption.

A further important object of the invention is to provide feed regulating means which will prevent foaming of the liquid .b'efore'its admission to the separator.

oylindrica'lin form and provided at its u p er and lower ends with concentric ho low stems, the upper stem 9 being internally threaded. e Passing through said stems and said valve-casing is a tube 1) which'is externally threaded and closed at its "upper end, and provided between its ends with openings I t, through which milk entering said chamber a through the inlet b passes into said tube b.

Q @The latter is open atits l0wer end, and telesco ically receives the tubular hollow'stem c o' "a float which is adapted tobe supportpipe a trifugal separator may be maintained rela the feed bowl e of the separator throughsaid tube a, the latter'being provided in its lower end with recesses 0 through which milk may flow laterally into said bowl 6 when said tube rests on the bottom thereof. of largeridiameter. than the outlet f of the bowl 6 so as to enable milk to be fed with sufficient rapidity toniaintain the said bowl partiallyfilled. .The said tube 6 is vertically adjustable in-said casing a and said tube ,0 is telescop cally'movable withinsaid tube 1) and when raised by the float acts as a valve to partially or entirely shut ofi'the flow of milk through saidopenings i, the degree of closure of the, latter being dependent upon the position of said tube b in'the casing a and upon I the level of milk in said bowl 6.

In Figs-2 and :3 I have illustrated a modi fied form ofconstruction of'my devioe'in which thesvalve casing a corresponds in diameter with the hollow-stems (IF-and a, and is semi-cylindrically enlarged at its-inletend as at a which communicates with the inlet The remaining parts accord in construction with similar parts shown in Fig. 1 and previously described, the only. essential Said tube a is pointof difference being that the. tube 6 has H but one opening '5 and this may bepartially or entirely closed by turning said tube 1) in either direction in anobvious manner; This enables the operator 'to' regulate the flow more rapidly, if desired, than would be possible with the construction shown in Fig. 1. By means of my device I am enabled to maintain the flow to the feed-bowl normally greater than the exhaust from the latter and thus prevent breaks in the feed and consequentagitation of the milk in passage where it is exposed to the air, and I thus prevent foaming of the inilk, prevention ofwhioh is Nery desirable to insure greatest efiicienoy of To these and other ends my said invention consists of a valve-casing it substantially the separator.

I claim as my invention:

1. In a liquid separator, a vertically disposed tubular member having connection between its ends with a source of supply of liquid, a member telescopically disposed within said tubular member and adjustable therein,v

there beingopeningS in said second member adapted to fcommunicate with said source of supply and coacting with the Walls of said first-named member to control said connection with said source of supply, a tube open at its ends and telescopically movable within said second member, and a float disposed on said tube at its lower end, adapted to lie with f in the feed bowl of the separator and be actuatedbyvariations in the level of liquid there-1 in toreciprocate said tube and control the supply of liquid through said openings.

2. Ina liquid separator, a vertically (lisposed tubular member enlarged between its ends and having connection atsaid enlar' ed portion, with a source of supply of liquid, a

member telescopically disposed within said tubular member and adjustable therein, there being openings in said second-member adapted to communicate with said source of sup ply and coacting with the walls ofsaid first named member-to control said connection with said source of su ply,'-a tubeopen at its ends and telescopical yinovable' within said. second member, and a float disposed on said tube at its lower end, adapted to lie within the feedbowl of the separator and beactuated by variations in the level of liquid there- I in to'reciprocate said tube, and control the supply of liquid through said openings.

3. In a liquid separator, a fixed vertically disposed tubular member enlarged between its ends and connected at said enlar ed'portion with a'source of upply ofliqui a tube disposed telescopically Within said tubular member and vertically adjustable therein,

i said tube being iilosed at its upper end and provided between its ends with openings communicating with said enlarged portionof said tubular member, a tube openat both Q ends telescopically movable in said, first: named tube and adapted tpcontrol the openings therein,-anda float carriedby said lastnamed tube and adapted't'o be-actuatedby variations in the. level of liquid in the feed. bowl of the separator .to impart movement to said las't-named'tube to regulate the-supplyof liquid through the openings in-said firstnamed tube. I

4. In aliquid separator, the combination with a substantiallyT-shaped member having threesiibstantially cylindrical arms one I of which is horizontally disposed and connected with the source of? supply of the liquid Ito be-separated, of a hollow cylindricalmember disposed telescopically and vertically adjustable Within the vertical arms of said T- shaped members and having an'openingkbe tween its ends through-which the li uid passes, a feed-bowl disposedbfelow saic T- shapedxmemb'er and having connectionwith the separating means, a vertically disposed feedpipe. movable telescopically within'said.
